Electromagnet invented by William Sturgeon

Only two years after Michael Faraday's ground-breaking work
developing an electromagnetic motor, William Sturgeon demonstrated
how it could be made of practical use by building the first
electromagnet that created such a strong magnetic force that it
could lift more than its own weight in iron. By wrapping a
horseshoe-shaped piece of iron in a coil of wire, and passing an
electric current through the wire, the iron became magnetised. He
was able to use a seven-ounce piece of iron to lift a full nine
pounds. One of the key things about Sturgeon's electromagnet was
that he was able to regulate and control it. This paved the way for
its use in all kinds of electric motors, as it is today.
